-INI PROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 141,881, dated August19, 1873; application filed March 14, 1873.

To. all whom it may concern:

Be it known that I, JAMES MARR, of Simcoe, in the county of Norfolk,Province of Ontario and Dominion of Canada, have invented certain newand useful Improvements in Plows, of which the following is aspecification:

This invention relates to certain improvements in self-holding plows,which are provided with a balance-wheel at the rear and a wheel at thefront, by which means furrows of the same width are at all times cut;and it consists in mounting the balance-wheel on a crank-axle hung in anarbor or bracket, so that the same may be removed with ease whendesired, and combining therewith a rack for holding the balance-wheelagainst theground when in use; and it further consists in attaching thegagewheel to a vertical bar connected to a slotted arm, so that thewidth of the furrow may be regulated, as will hereinafter appear.

In the drawings, Figure l is aside eleva tion. Fig. 2 is a plan. j

A is the beam; B,the mold-board and share 5 vand G, the back post orstay. D is the large balance-wheel, whose tire or periphery is madebeveled or V-shaped, the object to be presently explained. This wheel isattached to or moves on a crank-shaped axle, a,whieh passes underneaththe beam just back of the moldboard, and is secured thereto by a strapor hanger, b, in which it Works. This axle a is then bent back, andpasses to the rear in the form of a lever-handle, andvengages in thenotches or teeth in an upright catch or rack, el, fastened to the top orside of the beam. By the peculiar form of this combined lever andaxle-raising its lever end and setting it in the catchthe wheel D israised or lowered to accommodate it to any inclination or inequality ofthe ground to be plowed over.

The manner of attachment of the lever-axle to the beam is important, asby the use of the strap or hanger b it can easily be fastened on orunshipped by merely sliding on or back the hanger b, which is a greatadvantage. Should the wheel or axle need repairing or taking ofi', itcan be done in a few moments.

E is a thin and sharp gage-wheel working on one side of the beam, andattached tovan upright slotted piece, c, which in turn is attached to aslotted arm, f,'fastened to the beam at right angles thereto, forsetting the wheel higher or lower. This wheel is for thc purpose of'guiding and holding the plow, and when one furrow has been cut it runsin said furrow close up to the edge of the land. By this means furrowsof equal width may be turned at all times. The wheel may be adjustednearer to or farther from the beam to regulate the width of furrow.

I claim-7 1. The combined axle and lever a, coustructed in one piece,bent and arranged as described, and attached to the beam A by the hangerb, in combination .with the wheel D and rack d, as hereinbeforespecilied.

2. In a self-holding plow, the upright e, carrying the holdin g-wheel Eand attached to the slotted arm f, substantially as and for the purposedescribed. l

In witness whereofl I have hereunto signed my name in the presence oftwo subscribing witnesses.
